Add :
35.67 , 18.794 , 4.9 , 31.82

Answer

To solve the problem of adding the numbers 35.67, 18.794, 4.9, and 31.82 step by step, we will align the numbers by their decimal points and perform the addition.

### Step 1: Align the Numbers
Align the numbers by their decimal points:

```
35.670
+ 18.794
+ 4.900
+ 31.820
```

### Step 2: Add the First Two Numbers
Let's start by adding the first two numbers: 35.67 and 18.794.

```
35.670
+ 18.794
---------
```

- Start from the rightmost column (thousandths):
- 0 + 4 = 4
- Move to the hundredths:
- 7 + 9 = 16 (write 6, carry over 1)
- Move to the tenths:
- 6 + 8 + 1 (carry) = 15 (write 5, carry over 1)
- Move to the units:
- 5 + 1 + 1 (carry) = 7
- Move to the tens:
- 3 + 1 = 4

So, the sum of the first two numbers is **54.464**.

### Step 3: Add the Next Number
Now, we will add the result from Step 2 (54.464) to the next number (4.9).

```
54.464
+ 4.900
---------
```

- Start from the rightmost column (thousandths):
- 4 + 0 = 4
- Move to the hundredths:
- 6 + 0 = 6
- Move to the tenths:
- 4 + 9 = 13 (write 3, carry over 1)
- Move to the units:
- 5 + 4 + 1 (carry) = 10 (write 0, carry over 1)
- Move to the tens:
- 5 + 0 + 1 (carry) = 6

So, the sum of the first three numbers is **60.364**.

### Step 4: Add the Last Number
Finally, we will add the result from Step 3 (60.364) to the last number (31.82).

```
60.364
+ 31.820
---------
```

- Start from the rightmost column (thousandths):
- 4 + 0 = 4
- Move to the hundredths:
- 6 + 2 = 8
- Move to the tenths:
- 3 + 8 = 11 (write 1, carry over 1)
- Move to the units:
- 0 + 1 + 1 (carry) = 2
- Move to the tens:
- 6 + 3 = 9

So, the final sum is **92.184**.

### Final Answer
The sum of 35.67, 18.794, 4.9, and 31.82 is **92.184**.
